Description

  The present invention relates to an inkjet recording apparatus that records an image by ejecting ink onto a recording medium such as paper, and more particularly to an inkjet recording apparatus that can record an image on both sides of a recording medium.

  2. Description of the Related Art Conventionally, in an image forming apparatus using an electrophotographic system such as a copying machine or a printer, after forming an image on one side of a sheet, the sheet is conveyed again to the image forming unit without being discharged, and also on the other side. A double-sided recording type that forms an image is widely used. Such a double-sided recording type image forming apparatus includes a reversing unit for reversing a sheet on which an image is formed on one side, and a reconveying unit for reconveying the reversed sheet to the image forming unit. FIG. 5 shows a schematic configuration of a double-sided ink jet recording apparatus.

  In FIG. 5, reference numeral 100 denotes an ink jet recording apparatus. Here, a color ink jet printer that performs color printing is shown as an example. In the ink jet recording apparatus 100, four ink jet heads 1 a, 1 b, 1 c and 1 d are disposed in the vicinity of the transport belt 2. These inkjet heads 1a to 1d are provided corresponding to images of four different colors (cyan, magenta, yellow, and black), and ink tanks (not shown) filled with cyan, magenta, yellow, and black inks. ) Is installed.

  The ink jet heads 1a to 1d reciprocate along a guide shaft (not shown) spanned in the print width direction (paper surface direction in the figure), thereby sequentially forming cyan, magenta, yellow and black images, respectively. To do. The ink tank may be configured integrally with each of the inkjet heads 1a to 1d, or the ink tank may be configured to be separable so that only the ink tank is replaced when the ink runs out. Examples of the ink ejection method of the inkjet heads 1a to 1d include a piezo method in which ink is ejected using a piezo element (not shown), and a thermal inkjet method in which bubbles are generated by a heating element and the ink is ejected by applying pressure. It is done.

  A sheet (recording medium) 3 is accommodated in a sheet feeding tray 4 on the right side of the apparatus, and is placed on a loop-shaped conveyance belt 2 via a sheet feeding roller 5 and a driven roller 6 that is pressed against and rotated by the sheet feeding roller 5. To the positions of the inkjet heads 1a to 1d. A sheet made of a dielectric resin is used for the conveyance belt 2, and a belt in which both ends thereof are overlapped and joined to form an endless shape, or a belt without a seam (seamless) is used.

  The conveyor belt 2 is stretched between a belt roller 7 on the paper feed side (upstream side) and a belt roller 8 on the paper discharge side (downstream side), and the conveyor belt 2 rotates counterclockwise (in the direction of arrow X in the figure). ) Starts to rotate, the paper 3 is transported from the paper feed tray 4 onto the transport belt 2. At this time, the image writing signal is turned ON, and cyan ink is ejected onto the paper 3 by the most upstream ink jet head 1a at a predetermined timing, and a cyan image is recorded. Thereafter, magenta, yellow and black images are recorded by the inkjet heads 1b to 1d by the same method as described above. These four-color images are formed with a predetermined positional relationship that is predetermined with respect to the paper 3 in order to form a predetermined full-color image.

  The sheet 3 on which the full-color image is recorded is distributed in the transport direction by a branching member 9 provided at a branching portion that branches in a plurality of directions. When an image is recorded on only one side (single-sided recording mode), the sheet 3 is detached from the conveying belt 2 and conveyed as it is to the sheet discharge tray 12 provided outside the apparatus main body by the discharge roller 10 and the driven roller 11.

  On the other hand, when recording images on both sides of the paper (double-sided recording mode), the paper 3 is sorted by the branching member 9 toward the switchback device 13 and conveyed by rotating the feed roller pair 14 in the switchback device 13 in the reverse direction. After the direction is switched, the image recording surface is distributed to the double-sided conveyance path 18 with the branching member 9 swinging, and the image recording surface is moved by the conveyance belt 2 and the conveyance roller pairs 15 and 16. In the downward state, it is re-transported to the inkjet heads 1a to 1d. Then, after the next image is recorded on the surface of the sheet 3 on which the image is not recorded (hereinafter referred to as a non-image recording surface), it is separated from the conveyor belt 2 and discharged by the discharge roller 10 and the driven roller 11. It is discharged to the tray 12.

  In a double-sided recording type image forming apparatus, it is common to use the switchback device 13 as described above to invert the paper and perform recording on both sides, but in the case of inkjet recording, it takes time to dry the ink. Therefore, there is a problem that the image immediately after recording is rubbed by the feed roller pair 14 or the transport belt 2 and ink adheres to the feed roller pair 14 or the transport belt 2 or the image quality is deteriorated.

  In view of this, a method has been proposed for suppressing the contamination of the conveying means and the degradation of image quality due to the rubbing of the recording surface. For example, Patent Document 1 discloses that the paper after the recording on one side is temporarily removed from the apparatus main body during double-sided recording. An ink jet recording apparatus is disclosed in which paper is discharged into the apparatus, dried, and then fed again into the apparatus. Further, in Japanese Patent Laid-Open No. 2004-228867, in double-sided recording, an ink jet is used in which a sheet after recording on one side is stopped at a switchback position for a predetermined time, and ink ejected onto the sheet is dried and then fed back to the recording unit. A recording device is disclosed. However, in the methods of Patent Documents 1 and 2, since the ink is naturally dried, there is a problem that the drying time becomes long and the recording efficiency at the time of double-sided recording decreases.

  Japanese Patent Laid-Open No. 2003-228561 estimates the ink drying time on each side based on the range and density of the images recorded on both sides of the paper, and performs recording in order from the image with the shorter drying time. Ink jet printer double-sided recording method is disclosed, but the ink is naturally dried as in Patent Documents 1 and 2, so that the recording efficiency is not improved so much, especially when the drying time on both sides is comparable. It was not an effective method. In addition, when performing double-sided recording of a plurality of pages, there is a problem in that the recording sheets with the front and back reversed are mixed and discharged, and the consistency of page numbers cannot be obtained.

On the other hand, Patent Document 4 discloses an ink jet printer provided with a heater for drying ink, but the method of Patent Document 4 can prevent deterioration in image quality without reducing recording efficiency during double-sided recording. On the other hand, since the power consumption is increased by the heater, the running cost of the apparatus is increased.

Then, after the dried ink is dried, the switchback device reverses the front and back of the recording medium and transports it again to the inkjet head.

  According to the present invention, in the ink jet recording apparatus configured as described above, the adsorption of the recording medium by the adsorption unit is performed by electrostatic adsorption or reduced-pressure adsorption.

  According to the present invention, in the ink jet recording apparatus having the above-described configuration, the control unit performs a process from when an image is recorded on one side of the recording medium when the double-sided recording mode is executed until the recording medium is conveyed to the switchback device. In the meantime, the drying means is turned on.

  According to the first configuration of the present invention, the ink ejected on one side of the recording medium in the duplex recording mode is dried by the drying unit before reaching the switchback device. There is no risk of image quality degradation. In addition, since the ink can be dried while the recording medium is being transported, the image recording processing efficiency in the double-sided recording mode can be improved. In addition, in the single-sided recording mode, the drying unit should be turned off. Thus, the power consumption of the image forming apparatus can be reduced.

  Further, according to the second configuration of the present invention, in the ink jet recording apparatus having the first configuration, the recording medium is attracted to the transport unit by electrostatic suction or reduced-pressure suction, so that the transport unit can be easily configured. Adsorption of the recording medium can be realized.

  Further, according to the third configuration of the present invention, in the ink jet recording apparatus having the first or second configuration, the image forming apparatus is configured to minimize the ON state of the drying unit when executing the double-sided recording mode. The power consumption can be further reduced.

  Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing a configuration of an ink jet recording apparatus 1 of the present invention. Portions common to FIG. 5 of the conventional example are denoted by the same reference numerals and description thereof is omitted. The inkjet recording apparatus 100 includes a control unit 20, and an interface 21, ROM 22, RAM 23, encoder 24, motor control circuit 25, inkjet head control circuit 26, voltage control circuit 27, and the like are connected to the control unit 20. Has been.

  The interface 21 transmits / receives data to / from a host device such as a personal computer (not shown). Then, the control unit 20 outputs control signals to various control circuits based on the image data received via the interface 21.

  The ROM 22 stores a program for recording an image by driving the ink jet heads 1a to 1d, a control program for adsorbing a sheet to the conveyance belt 2 described later, and drying ink by the heater 31, and the like. . The RAM 23 stores image data received by the control unit 20 via the interface 21 in a predetermined area.

  The encoder 24 is connected to the belt roller 8 on the paper discharge side that drives the conveyor belt 2, and outputs a pulse train according to the rotational displacement amount of the rotation shaft of the belt roller 8. The control unit 20 calculates the rotation amount by counting the number of pulses transmitted from the encoder 24, and grasps the sheet feed amount (sheet position). Then, the control unit 20 outputs a control signal to the motor control circuit 25 and the inkjet head control circuit 26 based on the signal from the encoder 24.

  The motor control circuit 25 drives the recording medium conveyance motor 28 and the carriage movement motor 29 by the output signal from the control unit 20. The recording medium transport motor 28 is driven to rotate the belt roller 6 and rotate the transport belt 2 counterclockwise in FIG. 5 to transport the paper in the direction of the arrow X. The carriage moving motor 29 is driven to reciprocate the carriage 30 on which the ink jet heads 1a to 1d for the respective colors are mounted in the paper width direction.

  The inkjet head control circuit 26 transfers print data to the inkjet heads 1a to 1d based on the output signal from the control unit 20, and controls the ejection of ink from the inkjet heads 1a to 1d based on the transferred print data. To do. A recording process on the paper is performed by such control, control of transport of the paper by the transport belt 2 driven by the recording medium transport motor 28, and control of reciprocation of the carriage 30 by the carriage moving motor 29.

  The voltage control circuit 27 generates an alternating electric field by applying a voltage to the belt roller 7 on the sheet feeding side based on an output signal from the control unit 20, and electrostatically attracts the sheet to the transport belt 2. The electrostatic attraction is released by grounding the belt roller 7 or 8 based on the output signal from the control unit 20. The control unit 20 also performs ON / OFF control of the heater 31 that dries the ink ejected on the paper. Here, the voltage is applied to the belt roller 7 on the paper feed side, but the voltage may be applied to the belt roller 8 on the paper discharge side.

  FIG. 2 is a side sectional view showing a schematic configuration of the ink jet recording apparatus of the present invention. Parts common to FIG. 1 and FIG. 5 of the conventional example are denoted by the same reference numerals, and description thereof is omitted. In the present invention, the heater 31 is disposed below the conveyor belt 2, and the switchback device 13 is disposed on the downstream side of the heater 31. In the double-sided recording mode, the sheet 3 is transported so that the image recording surface faces the heater 31 while being attracted to the transport belt 2 by electrostatic suction, and the ink on the image recording surface passes through the heater 31. Dried. The heater 31 is preferably of a type that can dry ink in a non-contact manner, such as an infrared radiation type or a hot air blowing type.

  With this configuration, since the ink is dried by the heater 31 before the paper 3 reaches the switchback device 13, the image recording surface is rubbed when the paper 3 is switched back, and the feed roller pair 14 and the conveying belt 2 are contaminated. , There is no risk of image quality degradation. In addition, since the ink can be dried while the conveyance of the paper 3 is continued, the recording efficiency in the double-sided recording mode can be improved. On the other hand, in the single-sided recording mode, the power consumption can be reduced by keeping the heater 31 in the OFF state.

  The method of attracting the paper 3 to the transport belt 2 is not limited to electrostatic suction. For example, a large number of fine through holes are formed in the transport belt 2 and air is sucked from the inside of the transport belt 2 by a decompression device. Then, reduced-pressure suction for sucking the paper 3 may be used.

  FIG. 3 is a flowchart showing the operation of the ink jet recording apparatus of the present invention. With reference to FIGS. 1 and 2, the image recording process will be described according to the steps in FIG. First, when image formation is started by the user (step S1), the paper 3 is transported from the paper feed tray 4 onto the transport belt 2 by the paper feed roller 5 and the driven roller 6 (position A in FIG. 2). Then, a control signal is transmitted from the control unit 20 to the voltage control circuit 27, and a predetermined voltage is applied to the belt roller 7 on the paper feed side (step S2). As a result, the sheet 3 is electrostatically adsorbed on the transport belt 2.

  The sheet 3 is conveyed to the positions of the inkjet heads 1a to 1d by the conveyance belt 2, and ink is sequentially ejected from the inkjet heads 1a to 1d based on the image data received via the interface 21 (step S3). A full-color image is recorded at a predetermined position above.

  Next, it is determined whether or not the duplex recording mode is set (step S4). If the duplex recording mode is set, a control signal is transmitted from the control unit 20 to the heater 31 to turn on the heater 31 (step S4). S5). Then, the sheet 3 is conveyed downward while being attracted to the conveying belt 2 at the branching portion (position C in FIG. 2), and in the vicinity of the heater 31 (D in FIG. 2) with the image recording surface facing the heater 31. The ink is dried (step S6).

  When the sheet 3 passes in front of the belt roller 7 (position E in FIG. 2), a control signal is transmitted from the control unit 20 to the voltage control circuit 27 and the heater 31, and the belt roller 7 on the sheet feeding side is grounded. (Step S7) The heater 31 is turned off (Step S8). Then, the sheet 3 is separated from the conveying belt 2 and is once conveyed into the switchback device 13 by the conveying roller pair 15 and the feed roller pair 14.

  Next, while the feed roller pair 14 holds the rear end of the sheet 3, the feed roller pair 14 is reversed, and the branch member 32 provided at the branch portion F is swung to thereby switch the sheet 3 to the switchback device. Then, switchback is performed to convey the ink again from the inside 13 onto the conveying belt 2 (position B in FIG. 2) (step S9). Further, a control signal is transmitted from the control unit 20 to the voltage control circuit 27, and the grounding of the belt roller 7 is released (step S10). As a result, the front and back sides of the paper 3 are reversed and are attracted to the conveyor belt 2 again with the image recording surface facing downward.

  Then, the sheet 3 is conveyed again to the positions of the inkjet heads 1a to 1d with the non-image recording surface facing upward, and ink is sequentially ejected from the inkjet heads 1a to 1d based on the image data (step S11). A full-color image is recorded on the image recording surface. Thereafter, a control signal is transmitted from the control unit 20 to the voltage control circuit 27, the belt roller 8 on the paper discharge side is grounded (step S12), and the branch member 9 provided in the branch unit C is swung, thereby The sheet 3 is separated from the conveying belt 2 and is discharged onto the discharge tray 12 by the discharge roller 10 and the driven roller 11 (step S13).

  On the other hand, in the case of the single-side recording mode in step S4, after image recording is performed on one side of the paper 3, the belt roller 8 on the paper discharge side is immediately grounded (step S12), and the branch provided in the branch part C By swinging the member 9, the paper 3 is separated from the transport belt 2 and discharged onto the discharge tray 12 by the discharge roller 10 and the driven roller 11 (step S13).

  For the grounding of the belt rollers 7 and 8 and the ON / OFF control of the heater 31, a plurality of detection sensors for detecting the paper position along the conveying belt 2 are provided and controlled based on signals from the respective detection sensors. Alternatively, the reference time from the start of paper feeding until the paper passes a predetermined position is stored in advance in the ROM 22 or RAM 23 for each paper size, and the paper position is determined based on the reference time and the elapsed time from the start of paper feeding. It is good also as a structure which calculates and controls.

  Here, in the double-sided recording mode, the heater 31 is turned on when one-sided recording is completed, and the heater 31 is turned off together with the grounding of the belt roller 7 on the paper feeding side. However, for example, when the double-sided recording mode is set Thus, the heater 31 may be turned on, and the heater 31 may be turned off when the double-sided recording is finished and the paper is discharged onto the paper discharge tray 12. However, in order to further reduce the power consumption of the inkjet recording apparatus 100, it is preferable to use the control of FIG. 3 that minimizes the ON state of the heater 31.

  In FIG. 3, the belt roller 7 on the paper feed side is grounded in step S <b> 7 and the belt roller 8 on the paper discharge side is grounded in step S <b> 12, but the belt rollers 7 and 8 and the conveyor belt 2 are electrically connected. Therefore, in step S7 and step S12, if at least one of the belt rollers 7 and 8 is grounded, the adsorption of the paper to the transport belt 2 is released.

  In addition, this invention is not limited to the said embodiment, A various change is possible in the range which does not deviate from the meaning of this invention. For example, in the above-described embodiment, an example of an ink jet recording apparatus that transports paper in the horizontal direction from the paper feed tray 4 has been described as an example. However, the present invention is illustrated in FIG. The present invention can be applied in exactly the same manner to a vertical conveyance type inkjet recording apparatus that conveys a sheet from the sheet toward the discharge tray 1 on the upper surface of the apparatus.

  In FIG. 1, the input from the user is input from the outside of the personal computer or the like via the interface 21, but the configuration is not limited thereto, and the input is performed using an operation panel or the like provided in the inkjet recording apparatus 100. It doesn't matter. Further, the present invention is not limited to a serial head type ink jet recording apparatus in which the ink jet head reciprocates in the print width direction, but is a line head type ink jet recording apparatus in which a large number of ink jet heads are fixed at a predetermined pitch or more. Of course, the present invention can be applied not only to a color ink jet printer but also to a monochrome ink jet printer including only a black ink jet head 1d.

  The present invention relates to a loop-shaped transport unit that transports a recording medium, an inkjet head that discharges ink onto the surface of the recording medium transported by the transport unit, and the front and back of the recording medium with respect to the transport unit by switching the transport direction of the recording medium. An inkjet recording apparatus capable of executing a single-sided recording mode for recording an image on one side of a recording medium and a double-sided recording mode for recording an image on both sides of a recording medium. A drying unit that is disposed on the downstream side of the inkjet head and the upstream side of the switchback device and that dries the surface of the recording medium on which an image is formed on one side by the inkjet head; and an adsorption unit that adsorbs the recording medium to the conveyance unit; And a control means for controlling ON / OFF of the adsorption means and the drying means, the control means, When carrying out the surface recording mode, after drying the ink on the surface by the drying means while transporting the recording medium while adsorbed to the transporting means, reverse the front and back of the recording medium by the switchback device and transport it again to the inkjet head To do.

  As a result, the ink ejected on one side of the recording medium in the double-sided recording mode is sufficiently dried by the drying means and then reaches the downstream switchback device, so that the image recording surface is switched back before drying. It is possible to provide an ink jet recording apparatus that effectively suppresses contamination of the conveying means and deterioration of image quality due to rubbing against the conveying means, at a low cost. In addition, since the ink is dried while transporting the recording medium, the image recording processing efficiency in the duplex recording mode is also improved. The recording medium can be adsorbed to the conveying means with a simple configuration such as electrostatic adsorption or reduced-pressure adsorption.

  In the single-side recording mode, the power consumption of the ink jet recording apparatus can be reduced by turning off the drying means. Furthermore, if the ON time of the drying unit in the double-sided recording mode is set from the end of single-sided recording to the time of switchback, the power consumption of the drying unit can be minimized.
